### Log to File
To write the output to a file, simply redirect stdout and stderr to a file (or separate files).
Since this redirects all output, you will have to follow the contents of the log files to get realtime info:
```shell
# one shell window:
tail -F ./stdout.log
# another shell window:
./zfs-inplace-rebalancing.sh /pool/path/to/rebalance >> ./stdout.log 2>> ./stderr.log
```
